CronOs - Can't access admin.cronos.htb

hello.
I could access admin.conos.htb for the first time. but after doing reverse shell on this machine. I couldn’t access admin.conos.htb domain.

I tried curl admin.conos.htb in terminal and it shows output. But I can’t access using browser. Browser says “Server not found. We can’t connect to the server at www.crontos.htb.”

What is my problem?

me too mate having the same problem that after getting reverse shell i can’t connect through the browser, let me know if you got a solution for that
